DRV8411APWPR

Overview

The DRV8411APWPR is a dual H-bridge motor driver manufactured by Texas Instruments, designed for driving brushed DC motors, stepper motors, and inductive loads. It features a triple charge pump architecture enabling operation down to 1.65 V with 100% duty cycle capability. The device integrates current regulation via an external sense resistor and offers low on-resistance of 400 mΩ (typical) at +25°C. It supports PWM control interfaces compatible with 1.8 V, 3.3 V, and 5 V logic levels. Key protection features include under-voltage lockout, over-current protection, and thermal shutdown.

Feature Summary

• Triple charge pump architecture allows operation at low supply voltages down to 1.65 V
• Integrated current regulation compares internal reference voltage with external sense resistor voltage
• Low on-resistance enables efficient power delivery for high-current applications
• Comprehensive protection mechanisms including UVLO, OCP, and thermal shutdown

Applications

• Brushed DC motor control
• Bipolar stepper motor drive
• Solenoid actuation
• Inductive load switching

Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the HTSSOP-28 package variant when ordering. Confirm that the application voltage range aligns with the device's 1.65 V to 11 V specification. Ensure external components such as sense resistors and capacitors meet the requirements for the integrated charge pump and current regulation circuits. Check for AEC-Q100 qualification if automotive compliance is required, noting that standard variants may differ from automotive-grade versions.

Selection Notes

Select this component when a dual H-bridge solution is needed for compact motor control designs requiring low voltage operation. The integrated charge pump eliminates the need for external bootstrap diodes or complex gate drive circuits. Consider the 400 mΩ typical on-resistance for thermal management in high-current scenarios. The pin-to-pin compatibility with other DRV8xxx series devices allows for design flexibility and scalability across different current ratings without major layout changes.

Part Context

The DRV8411 belongs to Texas Instruments' DRV8xxx family of motor drivers, which are optimized for various industrial and consumer applications. This specific model provides a balance between performance and simplicity, featuring integrated protections and current regulation. It is part of a broader ecosystem that includes pin-compatible alternatives like the DRV8833 and DRV8410, allowing engineers to scale current capabilities while maintaining board footprint consistency.

Replacement Considerations

Pin-to-pin compatible substitutes include the DRV8833, DRV8833C, DRV8847, DRV8410, and DRV8411A. Verify that the alternative's on-resistance and current rating meet the application requirements. Note that the DRV8411A is also a 400 mΩ/bridge variant, offering direct functional equivalence.
